I'm makin an animation where I want to show the way of x-ray radiation through a device. To keep it doable for me I use multiple sources for "radiation"-particles, starting at one, flying to the next one, getting destroyed there, then new ones getting created. I basically created one radiation particle system and multiplied that for the other sources so I just had to change the source, the starting frame and the amount. Now I have encountered two problems:

A) Even though I deactivated any influence on the particles except for getting killed on certain objects, there is a phase where the radiation flies through a tube and they get slower and slower and stop moving as if there was some kind of resistance or friction. I cannot figure out the reason just why only THIS specific particle System has this problem. (note: another particle System exists, similar to this, particles flying through a tube and there is no drag)

B) I "kinda" fixed my problem by speeding up the particles of THAT particular System, then I tweaked the starting frames of the latter parts so it still looks kinda fluid. Now three particle Systems that were fully funtional before stopped working properly. Instead of the average of 2 particles per frame it should send out it only sends out 2 particles in the rendered time (about two thirds of the whole time I planned this animation to have). What reasons could that be?

I'd be happy if someone would know some ideas how to fix this.
